It's amazing!!! Once you set everything up, everything goes great and works perfectly!! It's well worth it, especially for the price it has... a great purchase.
Overall, a good, rugged budget alternative to a casio protrek. Getting the time, pedometer, altimeter, barometer, and temperature set for my location was easy despite mediocre instructions. Readings are reasonably accurate, though temperature requires taking the watch off-wrist. The compass seems close to my others but needs routine calibration. The dial thrives in bright sunlight but requires the backlight indoors.
Three recommendations for improvement:
Offer a positive dial module (ideally drop-in, as disassembly is easy).
Fix the fast-scroll behavior: when holding a button to change large values (like the altimeter), the numbers accelerate too quickly after 4-5 seconds, forcing you to constantly press and release to avoid overshooting.
Add a t2 seconds calibration option: my time 2 seconds randomly un-synced from the main time by 30 seconds, forcing a battery pull to reset. Allowing users to adjust t2 seconds would easily solve this.
Very good watch, it looks very sturdy and durable. I'm going to try it out; in fact, this is my second watch from this brand, and it has turned out to be very good and very comfortable.
